Having an issue with Onejar-Maven-Plugin
- by reverendgreen
I am trying to package a simple maven java project (uses javax.persistence api) into a single jar using the onejar-maven-plugin. I can run the program fine in eclipse; however when execute the onejar I get the exception below. If someone could provide some insight, that would be appreciated.
Thanks,
RG
